BACKING-PROTECTOR FOR BOOKS.

SPECIFICATION forming part of Letters Patent No. 704,554, dated July 15,1902.

Application filed June 4, 1901. Serial No. 63,110. (No model.)

To all whom, it may concern:

Be it known that I, STEFAN LITWIN, a subject of the Emperor ofAustria-Hungary, residing at Vienna, Austria-Hungary, have inventedcertain new and useful Improvements in Protectors for Backs of Books, ofwhich the following is a specification.

My invention has relation to a protector for book-backs, and in suchconnection it relates to the construction and arrangement of such aprotector.

Heretofore the backs of the covers of large books, such as lodgers orother books of record,have been provided with protectors, either singlyor in series; but these protectors when used spanned the backtransversely. They therefore were required to be made of a widthcorresponding to the width of the back of the book to be protected, andas the books were of varying widths, so far as their backs wereconcerned, it was necessary either to make the protectors of specialsize, as required, for each book or else keep on hand large quantitiesof varying sizes in the hopethat in the large number of protectors onecould be found to fit. Again, as these protectors spanned the back ofthe book-cover transversely and of necessity were rigid and unyieldingthe frequent opening or closing of the book resulted in either breakingthe protector or some portion of the book-cover.

All the above and other disadvantages are overcome by theback-protectors made according to the present invention.

The principal object of my invention is to provide a series ofprotector-plates arranged longitudinally of the book-back and each of alength required, the plates being arranged parallel to each other, butpreferably not abutting, and said plates capable of being readilysecured to the back of the book-cover.

The nature and scope of my invention will be more fully understood fromthe following description, taken in connection with the accompanyingdrawings, forming part hereof, in which- Figure 1 is an elevational viewof a part of the back of a book-cover, showing the sectional protectorembodying main features of my invention applied thereto. Fig. 2 is anend elevational view of Fig. 1, and Figs. 3,

4, and 5 are detail views illustrating one of the sections detached fromthe back of the cover.

Referring to the drawings, the sections are shown as five in number, andeach consists of a plate 1, having a rounded or curved exterior inpreferably three laminae or layers. The intermediate layer by preferenceis provided at itsbase with a plate 2,turned upward,

\ so as to straddle the lower edge of the back of the book, and thisplate 2 has prongs adapted to enter the book-back from the in teriorface of said back. A pin or rivet 3 traverses the rounded protector 1and is adapted to traverse the book-back and is secured to the same byupsetting or riveting the point of the rivet 3' against the interiorface of said back. The sections 1 are arranged longitudinally ofthe-back of the book and parallel to each other, but not touching. Bythis arrangement the flexibility of the back of thebook is not impaired,and yet the material of which the book-back is made is adequatelyprotected from wear.

Having thus described the nature and object of my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. In a device of .the character described, the combination with thebook-back, of a series of plates arranged longitudinally along a part ofthe exterior surface of the book-back and secured theretoparallel witheach other,
